Definitions
- the invention relates to filters for an air intake duct in a turbine, in particular a gas turbine.
- the invention relates to filters used in installations located in an environment rich in salt water.
- the air contains fine dust particles, the majority of which are of the order of a few microns. Inasmuch as it sucks up a considerable amount of air, a turbine is very sensitive to the negative effects of these dust particles.
- the atmospheric air may contain dust, mist, rainwater, salt water, carbon particles, etc. Therefore, the air sucked by the turbine is likely to cause corrosion and pollution inside the turbine duct and especially inside the air compressor that is first in the pipe. The performance of the compressor is reduced, thus generating a reduction in the efficiency of the turbine power generator.
- a filter is generally placed at the inlet of the air inlet duct of the turbine, so as to avoid the deposition of dust particles contained in the air in the compressor of the turbine .
- the retention corresponds to the ratio between the weight of the dust particles retained and the total weight of the dust exposed to the filter.
- the trace of dust corresponding to the relative characteristics of visual fouling due to the dust that has passed through the filter can also be considered.
- the object of the invention is therefore to provide a method and a system for controlling the performance of filters for an air intake duct of a turbine.
- the invention relates to a method of controlling a filter for an air intake duct of a turbine in which the filter is subjected to an incident stream of sprayed salt water, and measuring flux parameters on either side of the filter representative of the salt retention efficiency of the filter.
- the filter to be controlled is used in an environment other than the marine environment.
- the measurement steps are performed in a sequence of at least one test.
- measuring elements are moved in a test pipe in which the filter is placed.
- test sequences are performed.
- the filter can optionally be dried between the sequences.
- the filter is inclined by ten degrees with respect to the horizontal axis.
- each test includes measurement of salt concentration, saltwater droplet distribution, and amount of water and salt.
- the dry filter can be loaded with dust and at least one test sequence can be performed on the dust-laden dry filter.
- the invention relates to a control system of a filter for an air intake pipe in a turbine comprising means for injecting a stream of salt water sprayed to the filter.
- the control system further comprises flow parameter measuring members on either side of the filter representative of the salt retention efficiency of the filter.
- the measuring members comprise at least one member selected from a flowmeter, a conductivity meter, a photometer, a white light spectrometer, a humidity sensor, a pressure sensor and a particle measuring device.
- control system 1 comprises a test pipe 2 in which a test filter 3 is mounted and in which test steps are performed to determine the salt retention capacity of the filters. 3.
- the test pipe 2 is thus provided with a suitable support for the filter 3 (not shown) to position it transversely in the pipe in the path of an incident air flow illustrated by arrows F.
- a high performance filter 4 called a "HEPA" filter, is mounted at the inlet of the test pipe 2 so as to provide quality air in the pipe, in particular in different measuring zones A, B, C and D.
- the measuring zone A is located between the HEPA filter 4 and the filter to be tested 3 up to the zone B which is situated directly upstream of the filter 3.
- the zone C is situated directly downstream of the filter 3 and the Zone D is located downstream of zone C.
- Test pipe 2 comprises means 5 for injecting a stream of salt water towards filter 3 and an air transmission device (not shown) located upstream. of the test pipe 2.
- the control system 1 comprises flow parameter measuring members disposed on either side of the filter 3. These measuring devices are connected to a computer 6 which makes it possible to record the measurements made.
- the measuring elements comprise, for example, a flow meter 7, a humidity sensor 8, a static pressure sensor 8a, a white-light spectrometer 9, a graduated means 9a, a photometer 10, a conductivity meter 11 and a measuring means. measure 12 of the number of particles.
- a flow meter 7 a humidity sensor 8, a static pressure sensor 8a, a white-light spectrometer 9, a graduated means 9a, a photometer 10, a conductivity meter 11 and a measuring means. measure 12 of the number of particles.
- the flowmeter 7 is located upstream of the HEPA filter 4 and makes it possible to determine the flow rate of the incoming air.
- a humidity sensor 8 and a static pressure sensor 8a are located in each of the zones A and D.
- the white-light spectrometer 9 and makes it possible to determine the quantity of water in the zone A injected by the injection means 5 and the amount of water in the zone D.
- the graduated means 9a is located in the zones B and C and makes it possible to determine the quantity of water present in these zones.
- the photometer 10 is located in zone A and makes it possible to determine the salt concentration.
- the conductivity meter 11 and the particle number measuring means 12 are located in the zones B and C on either side of the filter 3.
- the conductivity meter 11 determines the salt concentration and the measuring means 12 makes it possible to determine the partial efficiency of the filter 3.
- the partial efficiency corresponds to the number of particles located downstream of the filter 3 compared to the number of particles of the same size located upstream of the filter 3.
- the pipe 2 as shown has, by way of non-limiting example, a height-adjusted shape so as to obtain a better distribution of the injection of the salt water on the filter 3.
- a first drop 13 forms an angle ⁇ with the horizontal axis
- a second vertical drop 14 forms an angle ⁇ with the horizontal axis.
- the angle ⁇ may be less than 7 ° and the angle ⁇ may be greater than 20 °.
- a straight line or with different angles ⁇ and ⁇ can also be considered to carry out the control of the filter 3.
- the filter 3 to be tested is inclined at an angle to the horizontal axis of the pipe 2. The angle may be 10 °.
- the filter 3 is mounted in the pipe 2 by sealed fastening means (not shown) in order to direct the flow of salt water only through the filter 3.
- the salt concentration injected by the injection means 5 may be, for example, 35 g / l.
- a first control step consists of tar setting the white light spectrometer 9 as well as the measuring means 12 of the number of particles.
- the filter to be tested 3 is not positioned in line 2.
- a flow of air is directed by the air transmission device through the HEPA filter 4 so as to obtain a good quality of air.
- air in the measurement zones A, B, C and D, then the salt water is injected by the injection means 5. The air flow makes it possible to obtain an incident flow of salt water sprayed towards the filter 3.
- the computer 6 reads the values of the white light spectrometer 9, the conductivity meter 11 and the means 12 for measuring the number of particles upstream and downstream of the HEPA filter 4, that is to say the values of the quantity of d water, salt concentration and number of particles.
- a second step is to insert and lock the filter 3 in the pipe 2, then the air flow is transmitted by air transmission device and the filter 3 is subjected to the incident flow of salt water sprayed by the injection means 5 for a predetermined period, for example three hours.
- a third step is to perform three tests for one hour.
- Each test includes measuring the amount of water by the white light spectrometer 9, measuring the salt concentration by the photometer 10 and measuring the number of particles by the measuring means 12 to determine the partial efficiency filter 3.
- each test lasts about fifteen minutes. An interval of about twenty minutes exists between each start of testing.
- the white light spectrometer 9 and the photometer 10 are moved in line 2 along the horizontal axis. During the tests, the measuring members 9 and 10 can be positioned in zone B, then in zone A, and in zone D.
- the three tests are repeated for about two hours, in order to obtain three measurements of each measuring device 9, 10 and 12 and to deduce an average thereof.
- test sequences Steps one through four are referred to later as "test sequences”.
- the fifth step is to dry the filter 3, for example by increasing the flow of air.
- the filter is dried for about twelve hours and its moisture content is checked.
- the test sequence is repeated at least once.
- the test sequence can be repeated up to four times.
- the 3 sec filter is loaded with dust at 450 Pa, for example of the ASHRAE type, and the test sequence is repeated at least two times, and then the filter is loaded again.
- the pressure drop should be checked regularly during the test.
- the invention which has just been described makes it possible to control a filter and to determine its efficiency of retention of salt and dust in a maritime environment, as a function of the amount of salt water upstream and downstream of the filter 4 , the amount of salt recovered upstream of the filter 4.
- the amount of saline water recovered upstream of the filter must be greater than the amount of saline water recovered downstream of the filter, the value of the salt water droplet efficiency and the amount of salt deposit must be greater than or equal to reference values. It can be noted, that there usually has a quantity of water, for example 25% of the initial quantity of water, which does not reach the filter 3.
- the invention is not limited to the control of filters used in a maritime environment, but makes it possible to control any filter.
